Question

There are 10 students. 30% of the students returned their calculators at the end of class. How

many students returned their calculator at the end of class?

Answer 1

Answer: 3

We can find 10% by dividing the number of students by 10.
10/10 = 1

We need to work out 30%, and we already have 10% so we just multiply 10% by 3.
1 x 3 = 3
So 30% = 3

Therefore, 3 students retuned their calculator at the end of class.

Answer 2

3 because 10% of 10 is 1 times by 3 fir 30% is 3 students
